Earth is an amazing planet, and the one that matters most to us. Let’s have a conversation about it.Mon, 02 Mar 2015 22:42:21 +0000hourly1http://wordpress.org/?v=4.1.1By: Carrie Sniderhttp://earthobservatory.nasa.gov/blogs/earthmatters/2011/07/12/are-you-ever-fooled-by-relief-inversion/#comment-13224

iQ score Visual Pattern Recognition . Skeptic at heart, test was too easy. Rock on.

It’s so common for me to see relief inversion I’ve just accepted it and remember the what is up is down.

I used to think I was the only one who occassionaly saw craters as “bumps.” I have found that this phenomenon is particularly evident in grayscale or B&W photos.

Although the Algerian false-color image struck me as being inverted, it’s obvious that the ancient arroyos are not ridges. Images of Mars, however, are vexing because it is not always immediately clear where the illumination is from. The high resolution Mars images would be well served if the direction of sunlight were explicitly noted.

Wed, 13 Jul 2011 13:39:43 +0000http://earthobservatory.nasa.gov/blogs/earthmatters/?p=185#comment-3240None of the photos submitted caused me any problems at intrepreting “up.” What do, and to a maddening degree, are planetary photos of craters. In many, many instances, I am unable to trick my head into seeing that the bottom of the crater is down, and not up. Rotating an image can sometimes help, and you can sometimes catch the point where your brain ‘flips’ up and down. Any others, the sun angle is such that no level of photo manipulation lets you see the scene properly. I’m hoping this is strictly a 2-D phenomenon, and that pilots, here or there, never have such problems…
